Huddersfield Town made their first move in the transfer market as a Premier League club by agreeing a club-record fee to sign Aaron Mooy from Manchester City in a deal that could be worth up to £10 million.
Mooy spent last season on loan with Huddersfield and was a key figure in their promotion-winning side, making 45 Championship appearances.
Paul Hirst of The Times adds that City have included both sell-on and buy-back clauses in the deal.
The 26-year-old Australia global was sensational for the Terriers last season and featured 51 times in all competitions, scoring four times and assisting on seven occasions as the club won promotion to the Premier League for the first time in their history.
Town's previous transfer record was set last summer when they shelled out £1.8m to sign 1860 Munich defender Christopher Schindler.
The sum Huddersfield is willing to pay surpasses what other Premier League clubs paid for high-profile Australians Mark Viduka, Harry Kewell and Brad Smith.
Mooy is on Confederations Cup duty with Australia in Russian Federation, with the Socceroos facing Group B games with Germany on June 20 and Cameroon three days later before facing Chile on June 26.
